ERROR_IPSEC_IKE_CGA_AUTH_FAILED - 13892 (0x3644)

Could not verify binding between CGA address and certificate.

Updated: Feb 21, 2026

Technical Background

The error code ERROR_IPSEC_IKE_CGA_AUTH_FAILED (13892, 0x3644) is encountered in the context of Internet Protocol Security (IPsec) and specifically within the Internet Key Exchange (IKE) protocol. IPsec provides security services for internet protocols such as IP, while IKE facilitates the establishment of secure connections between peers.

Error Details

This error indicates that there was a failure to authenticate a Certificate-based Global Address (CGA). CGAs are used in certain network configurations and provide an additional layer of security by binding a public key to a globally unique address. The authentication process involves verifying the relationship between the CGA address and the associated certificate.

Common Causes

  • Incorrect or Invalid Parameters: The parameters provided during the IPsec configuration might be incorrect, leading to this error.
  • Unsupported Operations: Certain operations involving CGAs may not be supported by the current system configuration or version of Windows.
  • Corrupted Data: If the certificate or CGA address is corrupted, it can lead to authentication failures.

Real-World Context

This error typically occurs during the establishment of a secure IPsec connection where CGA-based authentication is required. It could be encountered in environments that use CGAs for enhanced security measures, such as certain network topologies or specific security policies.

Is This Error Critical?

The criticality of this error depends on the context and the importance of the secured connection being established. In a high-security environment, this error might indicate a significant issue that needs immediate attention to ensure the integrity and confidentiality of data transmission.

How to Diagnose

  1. Review Operation Context: Ensure that the operation is performed in an appropriate security context where CGA-based authentication is supported.
  2. Validate Parameters: Verify that all parameters, including the CGA address and certificate, are correctly configured and not corrupted.
  3. Confirm Object Types: Check if the objects involved (e.g., certificates) are of the correct type and format as expected by the IPsec implementation.
  4. Verify Input Data: Ensure that the input data is valid and meets all necessary constraints.
  5. Check Limits or Constraints: Confirm that no system limits have been exceeded, such as maximum number of concurrent connections or certificate storage limitations.

How to Resolve

  1. Correct Parameter Usage: Ensure that all parameters are correctly set according to the expected values and formats.
  2. Adjust Operation Context: If the operation context is incorrect, adjust it to a supported configuration.
  3. Restore Data: If data corruption is suspected, restore from a known good backup or reissue valid certificates.
  4. Retry Operation with Valid Inputs: Attempt to establish the connection again using validated inputs and parameters.

Developer Notes

When dealing with this error, developers should ensure that their applications handle IPsec configurations correctly and validate all necessary parameters before attempting secure connections. Additionally, they should be aware of the limitations and supported operations within the current version of Windows or specific security policies in place.
